Fiber optic attenuators controllably attenuate optical signals according to user needs.
Mainly used in the evaluation, research, adjustment and correction of optical communication line systems.
The editor of Ningwang Technology will explain to you the classification of fiber optic attenuators.
1. Online optical fiber Attenuator
Online fiber optic attenuator is Optical communication devices with specific attenuation are provided according to the different needs of different projects.
Online optical fiber attenuators can be used in various optical fiber transmission lines to attenuate preset light intensity.
This kind of optical fiber attenuator is mainly used in optical fiber communication networks, optical fiber CATV networks, optical fiber data networks and optical fiber test systems.
The online optical fiber attenuator has high attenuation value accuracy, low additional loss, and better stability than other types. At the same time, its attenuation value can be adjusted according to your own needs.
2 .Fixed optical fiber attenuator
Fixed optical fiber The shape of the attenuator is more like an adapter. It is mainly used in optical fiber communication systems, optical fiber CATV and high-power optical device measurements.
It is mainly used through flanges. Jumpers with various connectors of FC, SC, ST and LC can be used. It is very convenient to install and simple to use, and is loved by many users.
3 .Yin and Yang type optical fiber attenuator
This fiber optic attenuator is a male-female device, which is the same as the fixed fiber optic attenuator. Supports a variety of connector methods such as LC, SC, FC and ST.
The female and male optical fiber attenuator adopts PC, UPC or APC grinding, and the attenuation value is 1-30dB.
It uses metal ion attenuated fiber technology to achieve the attenuation effect. It has the advantages of light weight, high precision, multiple forms, easy to use, small size and light power resistance.
Mainly used in: optical distribution frames. , Optical fiber network systems, high-speed optical fiber transmission systems, cable television (CATV) systems, long-distance trunk dense wavelength division multiplexing (DWDM) systems, optical add-drop multiplexers (OADM)
